Answer:
I<em>t D</em>e<em>p</em>en<em>d</em>s
Step-by-step explanation:
If you were to factor you would do what my teacher likes to call reverse foil so it would look like this (x-9)(x+4) so what you do is you brainsrorm to see what multiplies what to get that and 9*4=36 so that is how you factor -36 to find the -9
Hope this helps if I'm correct if not I will try to find the answer
Answer:
The total number of possibilities are 60.
Step-by-step explanation:
Given:
There are 6 digits and 3,7,9 are odd ones.
To Find:
How many possibilities are there for the rock's age
Solution:
Here condition is that number should start with odd digit
so there 3 number only as odd(3,7,9)
So it leaves 3 repeating numbers i.e.2
So permutation of 5 numbers with 3 odd numbers
So possible arrangement will be
nPr
n=5 ,r=3
So 5P3=5!/3!
And finally for all possibilities as
=3*(5!/3!)
=3*(20)
=60
Answer:
x = 0 and x = -2 are solutions of the given rational equation.
Step-by-step explanation:
We must solve the following rational equation:

Now we present the procedure:
1)
Given
2)
Compatibility with multiplication/Existence of the multiplicative inverse/Definition of division/Modulative property.
3)
Distributive property/
4)
Compatibility with addition/Existence of the additive inverse/Modulative property/Reflexive property
5)
Distributive property/
6)
Result
Now we check the rational equation with each root:
x = 0




x = 0 is a solution of the rational equation.
x = -2



x = -2 is a solution of the rational equation.
